Abstract

La présente invention concerne une technique de pompage d'amplificateur à fibre optique basée sur la diffusion de Raman stimulée (SRS), qui est destinée à des systèmes de communication optique comprenant une pluralité de signaux de pompe de longueur d'onde croissante qui sont injectés dans la fibre. Selon l'invention, les longueurs d'onde des signaux de pompe sont telles que chaque signal de pompe de la pluralité de signaux est amplifié en cascade par le signal de pompe de la longueur d'onde immédiatement inférieure tandis qu'il amplifie lui-même le signal de la longueur d'onde qui lui est immédiatement supérieure, le signal de pompe de la longueur d'onde la plus grande pompant à son tour un amplificateur à fibre optique dopée avec une terre rare situé à distance.
